Like symbols of reference indicate like parts wherever they occur. Heretofore in the use of combined pot and tank furnaces, or furnaces in which the glass is delivered from a tank-furnace into receptacles from which the glass is poured, drawn, or gathered, diliiculty has been experienced in obtaining glass of the proper quality and mixture from the pots or receptacles after they have been once emptied and refilled. The reason of this is that a certain amount of chilled glass adheres to the sides and bottom of the empty pots or receptacles, and this chilled and hardened glass, owing toits chilled and hardened condition, will not mix properly with the molten glass which is poured in to or flows into the pot or receptacle during the refilling operation.

'The object of my invention is to provide means for melting the chilled and hardened glass in the empty pots or receptacles before they pass to the refilling-station.

I will now describe myinvention so that others skilled in the art to which it appertains may employ the same.

in the drawings, 2 representsuth'e melting chamber of a tank-furnace a, and 3 the finingchamber, these chambers being se )arated from each other by the bridge-wall communicating through'the opening or openings 5 at or near the bottom of the bridgewall. At the opposite end of the fininchamber 3 is a trough 6, which exten s through a neck 7, that-joins the fining-chem her with a ot-furnace b. This pot-furnace l) is divide by a mantle 8 into two cham bersea pot-fillin chamber 8, into which the neck 7 and treug 6 open, and a pot-heating chamber 9, in which the empty pots are 4 and tank furnaces,

heated for the purpose of melting the chilled and hardened glass that adheres to the sides and bottom. In the floor'of the chambers 8 and 9 is a rotatory turn-table 10, mounted on a suitable shaft 11 in a pit 12 and provided with rotating mechanism 13. This table is designed and adapted to carry a series of pets or receptacles 14, which may be of any form. and. size, placed at suitable intervals on the table. Heating-fines 15 may be arranged at suitable intervals in the walls-of the melting and fining chambers 2 and 3, and a set of fines 16 is arranged in the walls of, the pot-heating chamber 9, by means of which the temperature in the heating-chamber may be maintained at a degree sufficiently high to rapidly melt the hardened glass in the empty pots. As already stated, the chambers 8 and 9 are separated from each other by a mantle 8, which extends from the roof of the chambers down to a point close to the surface of the table, leaving only suiiicient room for the rotation of the table 10 and the pots car ried thereon- In the wallfof the ot-ch am. her 8 is a door 17, by means of wine the ots containing molten glass are removed rom the pot-chamber and empty pots are intro- (luced.

he operation is as follows: The batch is fed in at the end of the tank-furnace and melted in the usual manner, the molten lass passing into the fining-chamber 3. From the fining-chamber the glass flows through the trough 6 to the pots 14, which as they are filled pass by the rotation of the table to the door 17, through which they are removedone by one and empty pots are put in their place. These empty pots by the rotation of the table 10 pass to the heating-chamber 9,

vwhere they are subiectcd to a heat of such intensity as to rapir. ly melt the chilled glass adhering thereto. These pots after being subjected to this heat pass from the heatingchamber with the adhering glass now in a molten condition, into the pot-chamber and under thetrough 6, where they are refilled with molten glass.

Although i have described my invention applied to articular forms of pot and do not desire to limit myself thereto nor do i desire to limit myself to any particular arrangement of the heating-charm )8! in connection with. the pot-furnace, as

other modifications of my invention will from the foregoing description suggest themselves to those skilled in the art.

The advantages of my invention result from the combined action of the pot and heating furnaces with their appliances whereby thepots are presented in proper condition for refilling.

-Wli:'it I. claim, and desire to secure by Lettcrs Patent, is p 1. The combination of a tank-furnace having a passage for conducting molten glass to the pot-furnace, a pot-furnace having a potiilling chamber and a pot-heating chamber, and a device for carrying the pots in the potiurnace from one chamber to the other; substantially as specified.

2. The combination of a tank iurnace having a passage for conducting molten glass to the pot-furnace, a pot-furnace having a potfilling chamber and a pot-heating chamber,

heating chamber to the pot-filling chain er;

substantially as specific In testimony whereof I have hereuntoset my hand.
